Man: Is that Mrs. Peterson those boys are interviewing?

Grace: Yes.

Man: And Mrs. Peterson is telling them about koala bears, is that right?

Grace:That's right!

Man: That's wonderful. Oh, i'm sorry, i didn't introduce myself. Bond. Bill Bond. I'm a wildlife biologist.

Grace: Oh! Do you work here?

Mr. B: no, I don't. But i am studying koala bears.
